Inventor Jae Tacke If m (ma W E M51815 3 seen that the lower ends of thebelts and 3| derive motion from a motion transmitting shaft 32. Thisshaft, as brought out to advantage in Figure 6, is provided with clutchpulleys 33 and 34, these fixedly keyed on the shaft. I now callattention to co-acting clutch members and 36 having brake bands, thesetelescoped into the belt pulleys 33 and 34 in an obvious manner. Each ofthese devices 35 and 36 is provided with a sleeve 31 which is splined onthe shaft. The sleeve is provided to accommodate a yoke 38 on one sideand a similar yoke 39 on the other. These yokes are operable by ashifter member 40 op-' eratively mounted in appropriate bearings orstands 4|. Incidentally, the shaft 32 is mounted for rotation inbearings 42 and said shaft is provided on its outer end with a pulley 43which is driven by a power supply belt 44. The belt 44 is operated byway of a pulley 45 on a drive shaft 46 which receives motion from a belt41 from an appropriate source.

From the description of the details so far given it will be seen thatthe power from an appropriate source received by way of belt 4'! drivesdrive shaft 46 and its pulley 45. Motion is transmitted from pulley 45to pulley 43 which turns the driven special clutch equipped shaft. Theshaft 32, the later clutch shaft is of the special construction shown inFigure 6 and therefore it is possible to shift the clutch means torotate the shaft in either one direction or the other. By pushing thecontrol lever 48 (see Figure 6) on its pivot 49 in a direction from, letus say, left. to right, the shifter 40 goes in the same direction andthis, through the yoke 38 disengages the clutch member 35. At the sametime it engages the clutch member 36 with the clutch pulley 34.

Moving the lever 48 and shifter rod 40 in the opposite direction fromright to left the opposite resultis attained. That is to say, the clutch36 is disengaged and the clutch 35 is engaged. These clutches arearranged so as to provide the desired forward and rearward drive motionsfor the carriage, the carriage taking its motion by way of the gears 26and 28 in mesh with each other and operated through the medium of shafts25 and 21 receiving motion from the belts 30 and 3| (see Figure 3).Thus, we have so far covered the frame structure, the carriage. meansand the shafts, pulleys, and clutch arrangements whereby the carriagemay be shifted back and forth in relation to the frame structure.

It is desirable to employ the shiftable carriage as a reciprocatorytable for holding and accommodating the Work. The work in the instantsituation happens to be a railroad tie, this denoted by the numeral 50in Figure-2 for example. Here we observe clamping devices suspended from'the end portions of the carriage and engaged with the oppositeendportions of the tie. Each clamping device is the same and a descriptionof one will suffice for both. Attention is therefore directed inparticular to Figures 6 and 7 where it will be seen that the preferredconstruction embodies a yoke 5| properly hung from the carriage 20, ashaft 52 mounted in a bearing 53 on a hanger 54 carried by the carriage,said shaft having a crank handle 55 at its outer end. Mounted on theshaft is a pinion 56 which meshes with the teeth of a rack bar 51slidably mounted in the yoke. The rack bar has a clamping head 58 on itsinner end which engages the adjacent end f the tie.

I next call attention to the group of four rotary cutter units ordevices mounted within the arranged in pairs.

confines of the frame structure and so positioned as to permit the log,tie or other work to be moved back and forth in relation thereto. It isdesirable to simultaneously surface all four surfaces of the tie and anysuitable tools or devices may be employed to accomplish this end. It isdesirable however to employ rotary cutters and these are For instance inFigure 4 we see the horizontal cutters 59 and 60. Then, in Figure 5 wesee the pair of close complemental vertical cuters 6| and 62. same inconstruction and a description of one will suffice for all. The cutterincludes a shaft 63 with a central polygonal portion 64 on whichsuitably arranged cutter blades 65 are mounted. The blades areindependent and of toothed construction as shown for instance in Figures11 and 12. The teeth are properly staggered and interrelated to producethe desired continuity in the cutting results. In addition, spacingcollars 68 are provided and these are mounted in place by clamping nuts61 and under the arrangement described it is possible to insert andremove cutter blades to adjust the total cutting surfaces to the widthand thickness of the work to be acted on. Each shaft is provided with apower reception pulley 68. The end portions of the shaft are mounted inaccommodation or adaptor blocks 69 having bolts 16 slidable inaccommodation slots H provided therefor.

In Figure 5 we see the slots H in a transverse angle iron 12 embodied inthe main frame structure. The slots at the top are in cross straps 13also attached to the main frame structure by way of the top angle irons,this as is Obvious. In Figure 4 a horizontal angle iron 14 is providedand this coacts with a horizontal cross piece 15 at the top and the twoparts 14 and 15 support uprights or posts 16 in which the stated slots Hfor the bolts H! are provided. The posts are fixedly mounted betweenparts 14 and 15. In addition, I provide cleats 11 wherever necessary toaccommodate the shiftable blocks. The main thing is that each cutterdevice is the same, is bodily adjustable and is within itself adjustableso that the number of blades can be increased or diminished asconditions require. The cutter devices are in horizontal and verticalpairs and this makes it possible to adjust the pairs properly toaccommodate variances in cross sectional width and thicknesses and alsomakes it possible to shave more-or-less off of top and bottom surfacesor side surfaces, as the case may be. Y

Coming now to the drive shaft again I call attention to the powertake-off pulleys l1 and 78 which operate motion transmission belts 19and 80. The belts are arranged in pairs and the pulleys are sufiicientlylarge to handle same and the belts are obviously so arranged and twistedas to supply motion to co-acting pulleys 68 on the four rotary surfacecutter devices 59, 60, BI and 62 respectively.

The simple pulley, belt and shaft arrangement makes it possible tosupply power from a single source to operate the drive shaft, to use thedrive shaft for simultaneously operating the pulley equipped arrangementof four cutter devices. In addition the driven shaft 32 with its pulleyarrangement and belts serves to supply the necessary motion for shiftingthe carriage back and forth. The carriage suspends thework and the workmoves in proper relation between the sets or pairs of cutter devices andEach cutter is the I all surfaces of the work are thus simultaneouslyacted on and desired results accomplished.

A careful consideration of the foregoing description in conjunction withthe invention as illustrated in the drawings will enable the reader toobtain a clear understanding and impression of the alleged features ofmerit and novelty sufiicient to clarify the construction of theinvention as hereinafter claimed.

Minor changes in shape, size, materials and rearrangement of parts maybe resorted to in actual practice so long as no departure is made fromthe invention as claimed.
